FLUID SPRAYER Russian patent published in 2013 - IPC A62C31/02 

FIELD: process engineering.

SUBSTANCE: invention relates to spraying of fluids and may be used in firefighting equipment. Fluid sprayer comprises hollow cylindrical casing with outer thread jointed to nozzle. Jets are arranged in nozzle in mutually perpendicular planes. Nozzle blind web has central throttling orifice with inclined at 45 degrees to nozzle axis. Cylindrical bead with outer thread is made on nozzle conical surface with angle at vertex making 90°. Cylinder-taper collar rigidly jointed with casing cylindrical section has two rows of throttling orifices. Some horizontal holes are made on cylindrical surface. Another row of orifices inclined at 45° is made on conical surface. Note here that projections of hole axes in said lines are spaced apart by angle varying from 7.5° to 60°. Cylindrical collar jointed with nozzle has a row of horizontal cylindrical throttling orifices. Note here that projections of hole and jet axes in said lines formed by pairs of mutually perpendicular vertical and horizontal channels are spaced apart by angle varying from 7.5° to 60°. Screw inner surfaces are located on cylinder-taper collars.

EFFECT: higher efficiency of spraying.
